An Application Developer Is Working on a New Calendar and Scheduling

An application developer is working on a new calendar and scheduling application. The developer wants to test new functionality that is time/date dependent and set the local system time to one year in the future. The application also has a feature that uses SHA-256 hashing and AES encryption for data exchange. The application attempts to connect to a separate remote server using SSL, but the connection fails. Which of the following is the MOST likely cause and next step?

A) The date is past the certificate expiration; reset the system to the current time and see if the connection still fails
B) The remote server cannot support SHA-256; try another hashing algorithm like SHA-1 and see if the application can connect
C) AES is date/time dependent; either reset the system time to the correct time or try a different encryption approach
D) SSL is not the correct protocol to use in this situation; change to TLS and try the client-server connection again
